needs two key things to balance a battery pack correctly: balancing circuitry and balancing algorithms. While a few methods exist to implement balancing circuitry, they all rely on balancing algorithms to know which cells to balance and when. So far, we have been assuming that the BMS knows the SoC and the amount of energy in each series cell.
Battery balancing equalizes the state of charge (SOC) across all cells in a multi-cell battery pack. This technique maximizes the battery pack’s overall capacity and lifespan while ensuring safe operation.
Simultaneous cell balancing can also be accomplished for multiple cells at once by means of comparator-based circuit solutions which facilitate the decision of bypass or energy transfer considering the entire battery pack. Anton Beck, “Why proper cell balancing is necessary in battery packs”, Battery Power.
An advanced method of managing an equal SOC across the battery pack’s cell is known as active battery balancing. Instead of dissipating the excess energy, the active balancing redistributes it, resulting in an increased efficiency and performance at the expense of elevated complexity and cost.
Control logic: Microcontroller or dedicated IC to manage the balancing process. Communication interface: This is for integration with the overall battery management system. Protection circuits: To prevent overcharging, over-discharging, and thermal issues. Temperature sensors: These monitor cell and ambient temperatures.
A deep knowledge of both the chosen balancing approach and the overall system structure of the BMS is needed for combining battery balancing techniques into a BMS. It consists of accurate control strategies, careful design, strong safety mechanisms, and complete diagnostics and maintenance methods.
